Referring now to Fig. 6,, diagram flow chart 600 is used to assemble of the present invention a kind of example embodiment of segmentation field with explanation.Specifically, in step 602, ingress switch 18 (Fig. 1) and auxiliary processor 24 are from the request of a telephone set receipt of call.Certainly, the part of call request is the out telephone number that is used for the identifying call letters destination in step 604.Segmentation and the description of auxiliary processor 24 references to storage 26 in step 606 so that originating number to be provided.In step 607, thereby system estimation segmentation and descriptor are determined numbering plan.Descriptor regulation numbering plan of being obtained and the represented content of jack per station field.Will be in step 607 according to this information and executing segmentation.For example, if describe dedicated line calling of indication, then will be according to the private numbering plan segmentation.Otherwise, if domestic call of descriptor indication then will suppose that receiving station carries out segmentation in the U.S. according to North American Numbering Plan.If this calling is an international call, then will use the international code that from descriptor, obtains for example country code and city codes etc. in view of the above.At last, in step 614, system transmits the information of setting up that comprises segment information from Fig. 5.
As mentioned above, can send segmentation and descriptor by the caller network with the integer sequence form that the figure place of each fragment size is formed in expression.Thereby descriptor can send the different implications that different coding is represented field with the form of cleartext information or coded message.The integer of noticing expression segmentation and descriptor can be encoded with the form that is suitable for most used signaling system and through Network Transmission.For example, segmentation and descriptor can be used (for example multifrequency) sound in IA5 (international alphabet) character, BCD (binary-coded decimal system) value, binary value or the band.As another example, will follow following analysis information at the international rear subscriber number " 15619973760 " that Germany receives:
1 (analyzing a numeral)
A (the indication country code is " 1 ")
3 (analyzing three numerals)
B (indication national goal ground code is " 561 ")
3 (analyzing three numerals)
C (indicating regional destination code to be " 997 ")
4 (analyzing four numerals)
D (the indication Subscriber Number is " 3760 ")
It is the most flexibly that this analysis and descriptor are provided, and does not need to carry out any modification for new numbering plan, if correctly transmit this information.
On the other hand, the analysis of use combination and descriptor will be transmitted data still less.The analysis that is used to make up and the example of descriptor are as follows.The predefine coding will be indicated the implication of different types of numbering plan and each field then, for example:
US1-NANP of expression
DE1-expression is used 2 country codes, 2 city codes, 3 station codes and 5 station numbers from an international call of Germany;
DE5-expression is used 2 country codes, 4 city codes and 7 station numbers from an international call of Germany;
Or the like; Certainly different coding can be used for representing different numbering plans.
The database for each code storage segmentation and descriptor is used in the point of destination.When the public telephone numbering plan of a country changes, must upgrade corresponding database.According to the segment information that is received, the domestic purpose switching equipment of Germany can local customary way by after first, the 4th and the 7th, inserting line separator ("-" character) formatted number.The domestic purpose switching equipment of Germany will show that this number is as follows to the telephone subscriber:
“1-516-997-3760”。
In another example, will send national number " 4084923911 " and analytical information by ingress switch:
3 (analyzing 3)
B (indication national goal ground code is " 408 ")
3 (analyzing 3)
C (indicating regional destination code to be " 492 ")
4 (analyzing 4)
D (the indication Subscriber Number is " 3911 ")
According to the analytical information that is received, the purpose switching equipment in Florida state Boca Raton city can format this number by front three being put into bracket and added line separator ("-" character) after the 6th with local customary way.The purpose switching equipment in Boca Raton city will show that this number is as follows to the telephone subscriber: " (408) 492-3911 ".
Referring now to Fig. 3, flow chart, control ringing detector 36 to determine a ring detection signal at square frame 50 microprocessors 38 (Fig. 2), according to this signal, when receiving switching signal, originating equipment receiving calling user information through calling party telephone net 20 at square frame 52.At square frame 54, microprocessor 38 receives segmentations and descriptor to be used by destination device from calling party telephone net 20, and step 52 and 54 receives expression rear subscriber number information and represents the segmentation of rear side phone number and a plurality of codings of descriptor from calling party telephone net 20.In step 56, information extraction Field Count from segment information, N (with the number of characters of every field) determines to determine the Field Count from the telephone number of calling party telephone net 20.
In step 58, the initialization field counter.System be each field groups should the correlated digital of field up to all fields by analysis in step 60-66.Particularly, in step 60, relatively count i and Field Count N to determine whether to finish analysis operation.After analyzing each field, field seperator for example underscore or bracket appears between the field of rear side phone number with character style.After analyzing each field, add one at step 66 field counter " i ", and flow chart returns step 60, at this relatively field counting and Field Count " N " once more.
If the field counter equals Field Count N, continue program circuit at square frame 68, the analysis of N field appears at this, provide square frame 70 to be used for application target equipment for example telephone set 14 and display unit 16 display of calling subscriber directory numbers, telephone set 14 and display unit 16 are connected to purpose network 22 and are used for from calling party telephone net 20 reception information.Shown in Fig. 7-9, can on display, show descriptor.Fig. 7 is illustrated in the full text form of the expression symbol that shows under each number field.In Fig. 8, use a database to explain different number field according to descriptor.Therefore, for example, second row can show " 49 " expression Germany, " 89 " expression Munich, and " 722 " are that station code and " 34570 " they are station numbers.Certainly database can also comprise the expression of station code and station code.Fig. 9 represents the display of a restriction Presentation Function.At this, one 2 row, the display of 16 characters is represented as in the cell phone of being everlasting and uses display.In this case, abbreviation is used to represent the implication of each field.For example, " CO " expression country code, " CI " expression city codes, " OFF " expression station code, " STAT " represent station number.
A kind of modification of Fig. 3 a presentation graphs 3 wherein at first sends segmentation and descriptor at step 52a, sends rear subscriber number at step 54a then.Then, segment information can arbitrary suitable method and description coded combination.And, can use the numbering plan coding as mentioned above.
The another kind of modification of Fig. 3 b presentation graphs 3.After analyzing first field, relatively comprise first field of its descriptor and first field and the descriptor of point of destination self in step 63.In step 65, if program circuit shunts to step 67.If then first field for example area code area code of equaling point of destination self will delete this field.Otherwise program circuit continues step 64, will insert a field seperator at this.Continue the described step 66 of Fig. 3.Therefore, all redundant informations will do not shown.Certainly, if first and follow-up field equal all fields of point of destination, only carry out relatively and the corresponding subsequent step.Any difference will stop this comparison, and for example, in an international number, the city codes difference if country code is identical does not then only show country code and will stop comparison, because station code belongs to different city codes.
As shown in Figure 4, can in the demonstration caller ID data-message that receives by the recipient, carry analytical information.As is well known, in first four second dead time, provide this data-message 400 in ringing cycle.Caller ID sends can use a kind of agreement, and this agreement is used the word of 8 bits, and every word opens beginning bit and an end bit limited boundary by one.As known in the art, data-message 400 comprises a channel occupancy signal 402 and a carrier signal 404.Classes of messages type-word 402 is with reference to message of calling identification data-message identification.The data word total length that message-length word 408 is specified subsequently.Data word can be encoded by ASCII, represents or comprise a moon field 410a, day field 410b, hour field 410c, minute field 410e and telephone number and segmentation and description field 410f.
